ASTM A358 TP304 Class1 Stainless Steel welded pipe introduction
What is ASTM A358 TP304 Class 1?
ASTM A358 is a standard developed by the American Society for Testing and Materials (ASTM) for arc-welded austenitic stainless steel pipes, designed for high temperature and high pressure applications.
TP304: Corresponding to the Chinese grade 06Cr19Ni10, it is the most commonly used austenitic stainless steel with good corrosion resistance and formability.
Class 1: refers to double-sided welding + 100% radiographic inspection of internal welds, strict quality control, and is suitable for critical pressure systems.
